VALVE-OPERATING MEANS.

Specification of Letters Patent.

Patented Oct. 5, 1920.

Application filed March 18, 1919. Serial No. 283,392.

construct a quick operating device inv combination with adupleX valve, in such a manner; that the said duplex valve, is'

opened or closed, during one turn or less, of the operating wheel or handle, of said quick operating device.

Figure l., is a vertical section of my improved apparatus, showing the duplex valve and the quick operating device, in lthe closed position.

Fig., 2., is a vertical section of my improved apparatus, showing the duplex valve and the quick operating device, in the open position.

Like letters and figures of reference, refer to like parts, in the several figures.

In Fig., l.,-'-B., is the valve-body; 1., is a coupling ring; 2., is a gasket; 3., is the valve-seat for the main valve M.; T., is a connecting tube; 4., is a gasket; N., is a nipple; 5., is a Gasket; C., is the crown to the valve-body d3.; I., is an inlet Vto the duplex valve M., R., V.; O., is an'outlet to the duplex valve M., R., V.; P., is a base-plate provided with a cylinder P'; t.,

and t', are spiral slots or grooves in partv P'; CZ., and CZ', lare drainage-ways in parts P., and P'; A., A', is an 4arm engagingthe spiral slots t., and t', and attached to the stem F., F; F., F', is a stem or shaft passing through the central aXis of parts P., and P', and connecting parts S., and R'; VQ., is the upper end of member F., F;, so arranged, as toV rotate with the member S., and at the same time, adapted, to allow a reciprocating movement, within the socket K., of the member S.; S., is a revolving stem or shaft within the member S'., and cooperating with the member F., F.,-said member S., is adapted to receive and engage an operating handle H., at its outer end,-saidrmember S., at its inner end, is provided with a socket K., adapted, to cooperate, with the part Q., of member F., F.'; s., is a gland disk, on member S., formingl a pressure proof bearing with member S.',--said gland disk s., is provided with a ring y., and an annular groove g.,s'a1d annular groove g., of said disk s., forms` the spacing distance, of said ring 1 of said disk s., from, its rotatable operating stem S.,said annular groove g., of said disk s., is also adapted, to receive the inner ring K.",l of member S.'; S.', is a removable stem-bearing-casing having the member S., therein,-S.', is provided with a stop o.,

'at its outer end, vto regulate the arc inscribed by the operating handle H,-S., is provided, at its inner end, with an outer ring K.', and an innerring K.", of unequal heights, with an annular groove K.", between said rings, K.', and K." H., is the 'operating handle adapted to engage, the

outer end of part S.; 7., and 8., is a groove at the lower end of part F., F', adapted to .receive the arm of ra small stop valve 10.,

arranged toclose the drainage-way d, when duplex valve M., R., V., is in the open position; e., e', is a coupler lioining the lower end of part F., F', to the part E., and adapted to have a sliding contact with part E.; E., is theV head of the part R'; R', is the apertured relief valve stem; M., is the main valve; R.,'is the relief valve; X., is a chamber adapted to house M., and R.; V., is the apertured casing, in the duplex valve; 0., 0'., 0"., is the inlet, the passageway and the outlet through part R'. (See my prior Patent No., 1042547, for duplex valve.)`

In operation, the handle H., rotates the 'part S., the part S., rotates the part F., F', through the intervention of part Q.; as the part F., F', is rotated upon its axis, the arm A., A', which is attached to the part F., F', and engaged in the spiral slots t., and t'., is made to follow the curve or lead of said slotsvt., andi', and in doing so, a reciprocating movement is imparted to the part F., F'. The said reciprocating movement of part F., F', actuates the apertured relief valve stem R'., thus in opening the duplex valve the downward movement of part F., F', imparts a similar downward movement, to the part R., thereby opening the passageway 0., 0'., 0"., through the apertured relief valve stem R'., this being done, the pressure in the chamber X., is relieved, when by a continued downward movement of parts F., F', and R', the main valve M., is carried away from its valve-seating 3., and when the handle H., has been rotated, one turn or less, and the arm A., A', has been carried the length of the spiral slots t., and Z, the duplex valve will bein the open position, with the parts related, as shown in Fig., 2. As the'part F., F', is moved to its open position, the said part F.,

F', is adapted, to coperate with mechanism,

dle, said casingV at its inner end .providedV .withan outer and an inner ring of unequal height, with an annular groove betweensaid rings, said casing provided with a rotatable, operating'stem thereinsaid rotatable stem adapted to receiveland engage an operating handle at its outer end, saidl rotatable stem provided with a gland disk, said disk provided with a ring and an annular groove, said -ringol' said: disk, adapted, to engage Vthe said annular groove of said stem-bearing-casing, lsaid annular groove of said disk,

adapted, to-receive the inner ring of said. stem-bearing-casing, said stationary, 'rota-I table, operating stem coperating with meansadaptedrto open a reciprocating '.Qfln ia valvejoperating means,-a baseplate surmounted vwith a tubular member arranged within a valve-body between the nipple and the crown of saidvalve-body, said tubular member and base-plate, adapted, to
